    <p>I use NSComparisonResult for searching through my array, but when I use NSDiacriticInsensitiveSearch, it cant find immediately Scandinavian alphabets like å æ ø, but it can find such alphabets as á etc. When I remove NSDiacriticInsensitiveSearch in options: , then my search bar can find å æ ø immediately, but ignore à and such. </p> <p>Is there any solution to this?</p> <p>EDIT 15 august: I believe using NSScanner (though I have no experience with this) in if logic for detecting å æ ø in searchstring, if they exist, then no nsdiactricinsensitivesearch. If no å æ ø in searchstring, then include nsdiactricinsensitivesearch in nscomparisonresult. I will try to implement this soon and give feedback if this works or not. </p> <hr> <p>My codes:</p> <pre><code>NSComparisonResult result; NSString *setext = searchText; NSScanner *scanner = [NSScanner scannerWithString:setext]; NSString *a = @"å"; while ([scanner isAtEnd] == NO) { if ( [scanner scanString:a intoString:NULL]) { [scanner scanUpToString:a intoString: NULL]; result = [mystr compare:searchText options:(NSCaseInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; } else { result = [mystr compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; } } </code></pre> <p>But it is a bit slower than my modification of JohnBrighton´s solution:</p> <pre><code> NSComparisonResult result; NSString *string = searchText; NSRange range = [string rangeOfString:@"æ"]; NSRange range2 = [string rangeOfString:@"ø"]; NSRange range3 = [string rangeOfString:@"å"]; if (range.location != NSNotFound || range2.location != NSNotFound || range3.location != NSNotFound ) //if ((range.location != NSNotFound) | (range2.location != NSNotFound ) | (range3.location != NSNotFound ) ) { { result = [mystr compare:searchText options:(NSCaseInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; } else { result = [mystr compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; } </code></pre> <hr> <p>Does anyone know whats the difference between || and | in if logic?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
